Frequently Asked Questions
Frequently Asked Questions
Practical answers for wallet, network, Web3, security and PoS usage. Blockchain transactions are generally not reversible by a wallet provider, and no one should ask for your seed phrase, private key or verification code.
Core questions across wallets, networks, Web3, security and staking.
What does a wallet primarily manage?
A wallet helps manage account control, addresses, network interactions and transaction construction while asset state is generally recorded on-chain.
Can support staff recover a wallet from my seed phrase?
No. Official staff will not ask for a seed phrase or private key, and you should not send them to anyone.
Is a screenshot a good private-key backup?
No. Screenshots may sync to cloud storage or be accessible to other apps. Offline backup is a safer default.
Why verify the network if the address looks the same?
Some networks use similar address formats while maintaining separate ledgers. The sending network must match what the recipient supports.
Is gas a fixed fee?
No. Gas depends on network conditions, transaction complexity and fee parameters.
What if a transaction stays pending?
Check the transaction hash and network state first. Confirm whether it was broadcast before attempting another transaction.
What is a transaction hash used for?
Use it in a suitable block explorer to check status, block height and confirmations.
Does connecting a DApp move assets?
A connection alone is usually not a transfer, but later signatures, transactions or approvals can create permissions or on-chain effects.
Are message signatures and transaction signatures the same?
No. Message signatures can support login or attestations, while transaction signatures authorize on-chain actions. Both deserve review.
What is risky about unlimited approvals?
A very large allowance can let a contract spend more tokens while the permission remains active. Use an appropriate scope and review it later.
Are all EVM networks the same chain?
No. They may share an execution environment and tools, but network state, gas assets and deployed contracts are separate.
Why do Layer 2 transfers need extra checks?
Transfers between a Layer 2 and mainnet or another network may involve bridges and waiting periods. Matching-looking addresses are not enough.
How can I recognize phishing?
Verify the domain, source and purpose. Stop any process that asks for a seed phrase, private key, verification code or remote device control.
Does Ethereum staking have a fixed APY?
No fixed return is guaranteed. Rewards vary, exits may take time, validators can face penalties and asset prices can fluctuate.
What happens if a validator goes offline?
The effect depends on network rules. Uptime can affect rewards, while prolonged or improper behavior can involve penalties.
What should I do with a suspicious approval?
Stop interacting with the suspicious site, inspect the approval target and amount from a trusted environment, and consider revoking permissions you no longer need.
